SURROUNDING WATER RIGHTS <br />Exhibit G-1 is a map of the permitted wells and adjudicated water rights within a half mile of the <br />site. Unregistered and unpermitted wells may be present on site. The well permit information <br />and adjudicated water right information are Exhibit G-2 and Exhibit G-3, respectively. <br />EXISTING DRAINAGES AT QUARRY <br />There are 3 separate drainages entering the proposed footprint of the quarry. Water originating <br />from these drainages will be managed in a phased approach. All three drainages are ephemeral. <br />Flows only occur when there is excess precipitation resulting in runoff. <br />The initial phases of quarry development will be above grade. Drainage will be routed through <br />the mining site either by piping or relocating and reconstructing open channels for conveyance. <br />All water will be returned back to the Arkansas River after appropriate management to remove <br />excessive sediment. Settling ponds will be the primary BMP used to clean storm flows from <br />these drainages. <br />Later phases of the quarry development will result in a closed basin that captures all drainage <br />from these three basins. Due to the steep slopes above the mine, it will be difficult to reroute <br />these drainages around the mining limits without excessive disturbance of the hillside. It is <br />proposed that any stormwater entering the mine site will be pumped and returned to the river for <br />the life of the mining operation. The operator has adequate water rights to augment any losses <br />that might occur while water is temporarily stored. <br />The quarry site will ultimately result in all drainage flowing into the pit once it is reclaimed and <br />turned into a reservoir. This event will happen many years in the future. It is anticipated that the <br />owner of the reservoir will be responsible for accounting of all captured water and passing <br />through any water that is stored out of priority. <br />WATER QUALITY <br />Please refer to Exhibit M for the status of the Parkdale Project's NPDES Permit. <br />Front Range Aggregates, LLC- Parlulale Quarry <br />DMG 112 Permi!
